Best Answer: You're wrong about what the arctan function is. arctan is that function that answers the question, What angle theta yields the tan (theta) = x? arctan 0 = 0 because the tan 0 = sin 0 / cos 0 = 0/1 = 0.
1 When we find an arctan of a reciprocal of an even-indexed Fibonacci number, we can use (A) to replace it by a sum of two terms, one an odd-indexed Fibonacci number and another even-indexed Fibonacci number. 2  Now we can use (B) on the odd-indexed Fibonacci number to replace it with two Lucas numbers instead.
